Q: I recently removed the carpet and pad from a house I purchased to uncover hardwood floors. As the temps and humidity rise there are oily blotches appearing. But nothing in the dining room where the wood floors were already exposed. Any idea what these oily areas might be and what do you suggest I do to fix it?
Also, have you had any experience with a Diamabrush disc for removing adhesive from hardwoods? I have pictures of the floor if you’d like to take a look.
A: These oily patches could be almost anything. I did one such floor once and after I removed all the old finish an oil, [probably] linseed kept oozing form the wood everywhere. In the end it didn’t cause an issue. On another one it wasn’t oil at all. It was pet urine. The previous owner had rolled some paint sealer on the hardwood and the urine was blocked beneath waiting to be release. That floor had to be replaced.
Pictures are always good. That carpet adhesive, if that is what it is, could be removed by a professional floor refinisher with his sanding equipment and rough sand paper.
